Structure, applications, and drawbacks of antibiotics | Britannica
Since the discovery of penicillin (1928), antibiotics have revolutionized the treatment of bacterial, fungal, and some other diseases. They are produced by many actinomycetes (e.g., streptomycin, tetracycline) and other bacteria (e.g., polypeptides such as bacitracin) and by …
13.1E: Antibiotic Classifications - Biology LibreTexts
Dec 24, 2022 · Antibiotics can be divided into two classes based on their mechanism of action. Bactericidal antibiotics kill bacteria; bacteriostatic antibiotics inhibit their growth or reproduction. One way that bactericidal antibodies kill bacteria is by inhibiting cell wall synthesis.
